Thanks Luca, I wasn't too far off! At least you knew what I was saying. So in this case, the parents were not married, is it customary to omit the mother's name on the birth certificate? I'm fairly sure the father's name is listed.

I have seen this statement many times in birth records. Would you please translate it? I was told that the "non parente" part was an assurance that the mother was not a relative of the father, which was a very important aspect. But, I am curious as to the actual translation of the whole sentence.

I hope you'll be able to understand my poor english.
For centuries in Itay the only form of marriage was the religious one. When Italy bacame united (in 1861) was created a new legal order and was stated to set up a Civil Status, the only way to identify a civil condition (birth, marriage, death, draft lists etc.). But people felt that the real marriage was still the religious, so for many years they continued to get married only in front of a priest. This problem was solved in 1929 with the "patti lateranensi" ( http://it.wikipedia.org/wiki/Patti_lateranensi ); until this time the State didn't recognize the religious unions, but it was obliged to identify a new born, also if he was son of a non-legal couple. And this is the case you posted. The registrar filled up the form only with the father's name, but he was obliged to verify that the mother was not a parent of the declarant (within the 6Â°) and that she wasn't already married with another man, so if then the couple decided to marry also with a civil union, they could recognize the children born in the meantime.
